APLANET 30pcs 50ml Flat-Bottom Plastic Graduated Vial Tube with Screw Cap

We bought these for a science fair project. They worked fine and held liquids well. The only problem is that the numbers rub off after a couple of washings (by hand)

Nothing really wrong with the vials themselves for the price. However, the picture shows that the vials are 1.5 inches wide, but they are 1 inch wide (38mm advertised; 28mm actual). This made them impractical for my use. Please correct the advertised width.

I purchased these for a project in our homeschool group. They worked great and the kids have been anle to use them several times now.
